Shadow DOM is a web standard enabling encapsulation of DOM subtrees in web components. It allows developers to create isolated scopes for CSS and JavaScript within a document, preventing conflicts with other parts of the page. Shadow DOM's key feature is its "shadow root," serving as a boundary between the component's internal structure and the rest of the document.
How to Scrape Data Off Wikipedia: Three Ways (No Code and Code)
This story was written by: @horosin. Learn more about this writer by checking @horosin's about page,
and for more stories, please visit hackernoon.com.
For a side project, I turned to Wikipedia tables as a data source. Despite their inconsistencies, they proved quite useful. I explored three methods for extracting this data:
- Google Sheets: Easily scrape tables using the =importHTML function.
- Pandas and Python: Use pd.read_html to load tables into dataframes.
- Beautiful Soup and Python: Handle more complex scraping, such as extracting data from both tables and their preceding headings.
These methods simplify data extraction, though some cleanup is needed due to inconsistencies in the tables. Overall, leveraging Wikipedia as a free and accessible resource made data collection surprisingly easy. With a little effort to clean and organize the data, it's possible to gain valuable insights for any project.

Ever wished there was a tool that could instantly turn your code into a clear, visual diagram? Well, that's exactly what NoReDraw does! Born out of a software engineer's frustration, this tool identifies key components like artifacts and configurations, and links them together to create a comprehensive architecture diagram. It's designed to be super customizable and easily extendable, ensuring your documentation stays up-to-date without the hassle of redrawing diagrams every time something changes.
Spring-based suites such as Spring Web Flux and Spring SSM are utilized to build a log anomaly detection system. This is a three-part series, with the foundation components covered in the first part. The subsequent parts will extend these components to enhance flexibility and robustness."
Why Open Source AI is Good For Developers, Meta, and the World

With past Llama models, Meta developed them for ourselves and then released them, but didn’t focus much on building a broader ecosystem. We’re taking a different approach with this release. We’re building teams internally to enable as many developers and partners as possible to use Llama, and we’re actively building partnerships so that more companies in the ecosystem can offer unique functionality to their customers as well.
I believe the Llama 3.1 release will be an inflection point in the industry where most developers begin to primarily use open source, and I expect that approach to only grow from here. I hope you’ll join us on this journey to bring the benefits of AI to everyone in the world.

Code Smell 257 - Simplifying Property Names By Removing Prefixes
This story was written by: @mcsee. Learn more about this writer by checking @mcsee's about page,
and for more stories, please visit hackernoon.com.
Avoid Using the Prefix "Collection" on Properties. Use Simple Names. Remove 'collection' from the name. Use plural names without the word 'collection.' When you prefix properties with terms like "collection," you introduce redundancy and verbosity into your code. This makes your code harder to read and maintain. Good design adds value faster than it adds cost.
